Everyone who is anyone in the Queens political realm joined newly elected Borough President Melinda Katz for her official inauguration ceremony last week at Queens College’s LeFrak Concert Hall at 65-30 Kissena Blvd.

Nearly every seat was filled and photographers lined the isles as numerous citywide representatives delivered their best wishes for her success.

Following a performance from Astoria’s Frank Sinatra High School chorus, the Forest Hills native was sworn in by Mayor Bill de Blasio with the help of Congressman Joseph Crowley.

"I would like to dedicate this to my parents," Katz said, after she was sworn in using her father’s copy of the Old Testament.

She thanked her family and boyfriend Curtis Sliwa for standing by her side throughout the election, who also looked on from the sidelines throughout the night.

"Curtis really became Mr. Mom during the campaign,” she said. “Every time someone would ask, 'Where is Curtis?' I would always say, 'Someone has to watch the kids.'"

Other representatives on hand included Public Advocate Letitia James, Comptroller Scott Stringer, State Comptroller Thomas DiNapoli and Senator Charles Schumer, as well as dozens of City Council members, community board chairs and local civic leaders.

Warren Schreiber, president of the Bay Terrace Community Alliance, said he expects Katz to focus on developing the business community in Queens with “responsible development.”

“That is the biggest, so that the people don’t have to really leave Queens,” Schreiber said. “Change is always exciting and we are looking forward to watching Queens continue to move forward.”

Jack Friedman, executive director for the Queens Chamber of Commerce, said he hopes Katz can help unite the borough in the City Council, Assembly and State Senate.

“We need to come together as a team, as a borough unit, and fight for borough-wide issues,” Friedman said.

All in all, Friedman said he is excited for the upcoming Katz administration.

“She brings so much energy, so much talent, so much experience and so much vibrancy,” Friedman said. “The role of the borough president is being the cheerleader of our borough, and having Melinda as our cheerleader is going to bring great things to this borough.”

Schumer made his entrance following the inauguration speech from the new borough president.

“Does anyone have any doubt that she is going to be one great borough president?” Schumer asked, before ripping up his planned speech. “Melinda, congratulations, good luck, Godspeed and God bless.”
